16. RS-232C Serial Interface

Note When the RS-232C serial interface is used, be sure to set the "Address ( f11 ) " to "( 00 )".

The RS-232C interface has the following two modes.

Stream mode Outputs data continuously and can be used for printing data.

Command mode Controls the scale using commands from a computer.

Set the parameters for the "Baud rate ( f4 )", " Output mode ( f5 )" and " Format

( f15 )", in the function table, in advance.

There are option cables as follows:

AX-KO577A-200 RS-232C cable, D-sub 25 pin, 2m

AX-KO1786-200 RS-232C cable, D-sub 9 pin, 2m
